"The NH-U9S heatsink stands 125mm tall and has a square footprint of 95x95mm. Weighing 618grams, the heatsink is built around five 6mm diameter heatpipes which are soldered to the aluminum cooling fins and copper base plate in typical Noctua fashion. "continue »

Zalman introduced its ZM-MFC2 multi fan speed controller last year at CES, and the reason we're reviewing it today are three-fold. For starters, the Zalman ZM-MFC2 digitally monitors four fans to +/- 10RPM and displays that data in real time.

The ASUS Triton 77 heatsink is one of the latest processor thermal solutions to come from motherboard manufacturing giant ASUS. The heatsink is equipped with a Sunon MagLev 92mm vapo-bearing PWM fan which runs at a very quiet 2300RPM.

The Scythe Shuriken (SCSK-1000) heatsink features copper heatpipes, high density stacked aluminum fins, a copper base and a low profile 12mm thick 100mm Pulse Width Modulation (PWM) fan. All that in a package that is 65mm tall.

Like the Ultra-120 that came before it, the Thermalright Ultra-120 Extreme applies fairly simple concepts to yield a well performing tower heatsink that doesn't have to generate much noise to
get the job done.

The Asus Triton 75 heatsink is intended to be used with a 120mm fan of your choice. The 395 gram heatsink is uses four 6mm diameter copper heatpipes to support a 120x120mm aluminum fin array above the CPU socket.

The Xigmatek HDT-S1283 heatsink features three heatpipes in direct contact with the top of the processor, resulting in one very potent CPU cooler. The technique is called heatpipe Direct Touch, and for today's class of heatspreader capped processors it's the only way to go.

The idea is that one relatively low RPM fan is going to have a hard time maintaining a good volume of airflow through the heatsinks' fins, so the second helps draw the warmed air through and alleviate any loss in velocity.

At least we would assume all that is accurate after testing the Scythe Infinity heatsink... The Infinity is a big heatsink for sure; it stands 155mm tall, 125mm wide and about 114mm deep with its 120mm 1200RPM fan. The scale tips at 960 grams, or just short of a kilogram.
